Accessing Microsoft Teams using organizational or personal credentials
Could you provide the exact error message or error code you receive when trying to access the Nature's Grace and Wellness tenant?
When you accepted the invitation, were you prompted to consent to the permissions and set up MFA, as shown in the screenshot below? Did the process display the guest account?
If the invitation was sent to your Gmail address, make sure you sign in using the same Gmail address you used to accept the invitation. The guest account may have an internal UPN in the format username_gmail.com#EXT#@tenant.onmicrosoft.com.
If the issue persists, ask the tenant administrator to verify your guest account in Microsoft Entra ID, confirm that the invitation was redeemed successfully, and check your access to the relevant Teams resources. As a forum user, I cannot access or inspect their tenant configuration.
